In short: No, the old Commodore went bankrupt and never came back. The new Commodore you see now is a company that bought the naming rights. They are trying to make a buck on retro-people by designing computer cases that look like the old Commodore ones. There is even an effort similar to this for the Amiga brand, you will be able to buy 'modern' versions of the Commodore Amiga systems, which is nothing more than a generic case with a PC inside, and there is even talk of a Linux OS with a WorkBench theme.
So basically, if you are looking for the old Commodore, you can still buy used stuff on ebay, or simply run an emulator. What you might be interested in is checking www.pouet.net for demoscene releases, people still actually make software for the Commodore machines and release it every now and then.
Also, if you like the SID music of the Commodore, you might want to check out the High Voltage Sid Collection; see links
There are still large Commodore and Amiga communities around on the IRC and web forums, you might want to keep an eye out for those if you are interested in reconnecting with the community. They will also be able to answer most questions you might have about how to best find hardware/software.
For example vesalia and amigakit has some interesting products, for example a joystick with a built-in C64.
No. The commodore line of computers were a different company; Commodore.Radio shack's computers during that time were the TRS-80 line.

Yes there is an operating system called Lunix, not to be confused with Linux. Lunix is a Unix-based operating system for Commodore 64 and Commodore 128 computers.

The rank of "Commodore" is an honorary one, not an actual Navy rank (at least not in today's Navy). A Commodore is a Senior Navy Captain who is a Squadron Commander of a group of ships, submarines, aircraft, etc. Though the officer is addressed as "Commodore", he/she still wears the rank of Captain.
Yes, definitely computers will exist.
